I wanted to see the real speed at the SAX interface after a little too

Browse Source 
* testSAX.c: I wanted to see the real speed at the SAX interface
  after a little too many Ximianer started complaining about the
  parser speed.
  added a --quiet option:
  paphio:~/XML -> ls -l db100000.xml
  -rw-rw-r--    1 veillard www      20182040 Mar 20 10:30 db100000.xml
  paphio:~/XML -> time ./testSAX --quiet db100000.xml
  3200006 callbacks generated
  real	0m1.270s
  Which means 16MBytes/s and 3Mcallback/s
